As they return to Washington this week from their August recess, House Republicans on the Ways and Means Committee have their work cut out for them. Their job is to draft a major tax-cut bill for Congress to pass, ideally by year-end, to avoid closing out 2017 without a single big legislative win. The policy objective is to steeply cut tax rates for businesses and wealthy individuals. The political aim, and the point of President Trump’s speech last Wednesday, is to persuade the men and women in the Trump working-class base that a tax cut for the wealthy would be good for them, too.
It would not be, and to pretend otherwise, as Mr. Trump did, is to substitute propaganda for discourse. Mr. Trump’s claim that tax cuts will propel economic growth and lift wages ignores the consensus view of economists, which is that multitrillion-dollar tax cuts, as envisioned by Mr. Trump, are not a stable or reliable way to do either.
